Letters Patent No. 7 4,058, dated February 4,1868;

IMPROVED VELOGIPEDE.

T0 ALL WHOM IT MAY CONCERN: n

Be it known that I, LOUIS DEROZIER, ofthe city, county, and State of New York, have'invented a newr and improved Vel-ocipede; and I do 'hereby declare that the following is a full, clear, and exact description thereof',

-which will enable those skilled in the art to make and use the same, reference being had to `the accompanying drawings, forming part of this specification, in which- Y Figurel l represents an inverted plan view of'my improved velocipede.

Figure 2 is a vertical longitudinal section ofthe same, the plane of section beingindicated by the linexz, {ig.v1.

Figure 3 is a'vertical transverse section of the same, the plane of section being indicated by the line y y, iig. 1. Similar letters of reference indicate corresponding parts. This invention relates to a new velocipede which may be driven by muscular or other power, and which is so arranged-that its cranks cannever become useless by' remaining on the dead-point, and that it can'be easily turned.

The invention consists in the use of'a divided rear axle, each hind wheel being mounted on a separate axle. Each axle is provided with two or more cranks, and is operated by' means of levers or treadles hinged to the platform of the wagon. n y

The object of this double rear axleis that, when one becomes unmanageable, by`remaining on the deadpoint, it will be turned forwardby the motion of its wheehwhich turns because the other axle is operated. The

Y double axles also permit 'an easier steering, although ,the front axle is provided with a fthwheel,and can be turned around the king-bolt by means of a crank Yarranged on the same. 4

The invention also consists in the manner of hanging the rear-axle. The bearings for the same are arranged in springs, which are suspended from the platform of the wagon. Great elasticity is thereby obtained, and the downward motion of the platform, during 'each stroke upon the operating-levers-or treadles will, by compressing the springs, aid in turning the rear axle off the dead-point.

A. represents the platform of the wagon, which may be constructed in any suitable manner, of suitable.

material and dimensions.r From its under sideare suspended, not farfrom its rear end, and in line with each other, three or more semi-elliptical or othersprings, B, in which the bearingsfor 'the rear axle are arranged. This rear axle consists oi' two pieces, C and C, each carrying awheel, D, near its outer end, and eachhaving its bearings in one of the outer and in the inner spring, B, asis clearly shown in iig. 3. TheV wheels D are mounted on their respective axles, so as to revolve with the same. Each axle, C C', has two or more cranks, a a, as shown. Each of these is connected by a rod, b, with a lever, E, which is hinged to the platform, as shown.` Thus, as one o f the levers is depressed at'its free end, the respective axle will make one half turn, and

the free end of the other lever' will be raised, so that the same may, i'o'r the next half turn, be depressed. Two

or more such cranks and levers may be provided on each section of the rear axle, and each lever may, by a'rod,

d, be connected with a similar lever, J, as shown, to which actual power is applied. '.llle same may be operated by muscular or other power. The front axle, F, is hung in springs, K K, suspended from a horizontal fifths` wheel, G, ina similar manner as the axles C C are hung in the' springs B.- The fifth-wheel is., by a..king-bolt,V

H, secured to the front portion of the platform A. The front wheels-I are hung to it in the ordinary manner. The bolt H has a crank, c, at its upper' end, by 'which the axle may be turned and the whole apparatus steered. By turning' butone of the axles, C C', and letting the other remain stationary, the device may also be steered, it turning, in that case, around the stationary wheel.

I claimv as new, and desire to secure by Letters Patentl. Providing a velocipede with a rear axle, which consists of two sections, C C', each turning independent of the other, substantially .as and for the purpose herein shown and described.

2. Providing the bearings for the axlgs C Cl and F, or either, directly in the springs B and K, substantially as and for the purpose herein shown and described.

3. The crank-axles C C and wheels D, when arranged as described, in combination with the springs B in which the bearings for the said axles are provided. l

4. The above, in combination with the front axle F, wheels I, and king-bolt H, having a crank, all made and operating substantially as and for the purpose herein shown and'described.

i LOUIS DEROZIER.
